That's the stupidest article I've ever read. It says the UK ******* rate is five times the USA rate and the truth is exactly the opposite.
"There were a total of 17,284 reported ******* and non-negligent manslaughter cases in the U.S. in 2017".
UK "There were 719 homicides – murderand manslaughter – in the year to June, a 14% increase from 630 in the previous year excluding exceptional incidents in 2017".
Your population is about 5 and a bit times ours, so adjust our ******* rate to about 3500, which is a bit more than a quarter of yours.
Well, if you actually read the article then you would see that the claim "the UK is 5 times more violent" isn't actually true. The numbers are played with to mislead. But the fact that the US has 5 times the population than the UK, obviously our crime rate will be higher.
